Kapiti Coast District Council is considering charges against the owner of two pit bull-type dogs that attacked two Otaki women.

The women, aged 48 and 67, were attacked in Moana St, Otaki Beach, about 3.15pm on Wednesday.

The first victim suffered extensive bites to her arms, legs and neck, while the second received a severe gash and tearing to her right thigh.

Both women have undergone surgery in Palmerston North Hospital.

Council community services group manager Tamsin Evans said it was a severe attack that shocked dog control officers. Once the owner had been interviewed officials would consider prosecution under the Dog Control Act, which carried a maximum fine of $20,000 and up to three years' jail.

Council dog control officers seized the dogs at the attack site. If there was a conviction, the court would order the destruction of the dogs unless the owner agreed for them to be destroyed.
